OK, so it's possible, thank you.

But how does Alice load the key into the manager?
Suppose she has the secret key stored somewhere in a
file or as a byte array (8 bytes for DES, e.g.).
Does she have to call xmlSecSimpleKeysMngrAddKey and
provide a keyPtr structure as the 2nd parameter? In this
case, would she have to construct the keyPtr herself?

Yes, it is possible. If you know how to exchange symmetric
(DES, HMAC, AES,...) keys between Alice and Bob then
you can specify the key using <ds:KeyName> element
of <ds:KeyInfo>. In particular, in XMLSec case, Alice should
load the key into keys manager and add <ds:KeyName> node
when you are signing/encrypting document. Bob simply loads
this key into keys manager and XMLSec "magically" finds it
when it decrypts/verifies the message.
